Using ancient compilers (gcc-4.5 or older) on ARM, we get a link failure with the vfio-pci driver:
ERROR: "__aeabi_lcmp" [drivers/vfio/pci/vfio-pci.ko] undefined!
The reason is that the compiler tries to do a comparison of a 64-bit range. This changes it to convert to a 32-bit number explicitly first, as newer compilers do for themselves.
